/**
 * @class   vtkImageWrapPad
 * @brief   Makes an image larger by wrapping existing data.
 *
 * vtkImageWrapPad performs a modulo operation on the output pixel index
 * to determine the source input index.  The new image extent of the
 * output has to be specified.  Input has to be the same scalar type as
 * output.
